Description

[0002] At present, the structure of the clamping device in the traditional winding machine includes: a rigidly connected fixed top core and a movable top core. When clamping, the fixed top core is first inserted into the mounting hole on one side of the take-up drum, and then the movable top core is inserted into the mounting hole on the other side of the take-up drum. During the clamping process, since the fixed top core and the movable top core have no elasticity, the clamping force between the fixed top core and the movable top core is difficult to control, and the take-up reel is usually a plastic part. If the clamping force is too small, it is not conducive to transmission, and if the clamping force is too large, the take-up reel will be deformed and damaged. In addition, during clamping, only the fixed top core and the movable top core are in contact with the take-up reel, and the clamping contact surface is too small, which makes it easy for the take-up reel to deflect when rotating, causing damage to the take-up reel and shortening its service life. In addition, the positioning of the take-up reel is also very troublesome. When the take-up reel is installed on the fixed top core, the positioning through hole on the take-up reel must be aligned with the positioning threaded hole on the take-up machine by observation, and then the screws are passed through the positioning through holes on the take-up reel and tightened on the take-up machine.
